"git repo structure" command learns to report maximum values on various aspects of objects it inspects. * jt/repo-structure-extrema: builtin/repo: find tree with most entries builtin/repo: find commit with most parents builtin/repo: add OID annotations to table output builtin/repo: collect largest inflated objects builtin/repo: add helper for printing keyvalue output builtin/repo: update stats for each object
2026-03-02builtin/repo: collect largest inflated objectsJustin Tobler
The "structure" output for git-repo(1) shows the total inflated and disk sizes of reachable objects in the repository, but doesn't show the size of the largest individual objects. Since an individual object may be a large contributor to the overall repository size, it is useful for users to know the maximum size of individual objects. While interating across objects, record the size and OID of the largest objects encountered for each object type to provide as output. Note that the default "table" output format only displays size information and not the corresponding OID. In a subsequent commit, the table format is updated to add table annotations that mention the OID. Signed-off-by: Justin Tobler <jltobler@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>

2026-02-14repo: add new flag --keys to git-repo-infoLucas Seiki Oshiro
If the user wants to find what are the available keys, they need to either check the documentation or to ask for all the key-value pairs by using --all. Add a new flag --keys for listing only the available keys without listing the values. Signed-off-by: Lucas Seiki Oshiro <lucasseikioshiro@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2026-02-14repo: rename the output format "keyvalue" to "lines"Lucas Seiki Oshiro
Both subcommands in git-repo(1) accept the "keyvalue" format. This format is newline-delimited, where the key is separated from the value with an equals sign. The name of this option is suboptimal though, as it is both too limiting while at the same time not really indicating what it actually does: - There is no mention of the format being newline-delimited, which is the key differentiator to the "nul" format. - Both "nul" and "keyvalue" have a key and a value, so the latter is not exactly giving any hint what makes it so special. - "keyvalue" requires there to be, well, a key and a value, but we want to add additional output that is only going to be newline delimited. Taken together, "keyvalue" is kind of a bad name for this output format. Luckily, the git-repo(1) command is still rather new and marked as experimental, so things aren't cast into stone yet. Rename the format to "lines" instead to better indicate that the major difference is that we'll get newline-delimited output. This new name will also be a better fit for a subsequent extension in git-repo(1).

Similar to a prior commit, extend the keyvalue and nul output formats of the git-repo(1) structure command to additionally provide info regarding total object disk sizes by object type. Signed-off-by: Justin Tobler <jltobler@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2025-12-18builtin/repo: add inflated object info to keyvalue structure outputJustin Tobler
The structure subcommand for git-repo(1) outputs basic count information for objects and references. Extend this output to also provide information regarding total size of inflated objects by object type. For now, object size by object type info is only added to the keyvalue and nul output formats. In a subsequent commit, this info is also added to the table format. Signed-off-by: Justin Tobler <jltobler@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2025-12-05repo: add -z as an alias for --format=nul to git-repo-structureLucas Seiki Oshiro
Other Git commands that have nul-terminated output, such as git-config, git-status, git-ls-files, and git-repo-info have a flag `-z` for using the null character as the record separator. Add the `-z` flag to git-repo-structure as an alias for `--format=nul`, making it consistent with the behavior of the other commands.

2025-12-05repo: use [--format=... | -z] instead of [-z] in git-repo-info synopsisLucas Seiki Oshiro
The flag -z is only an alias for --format=null and even though --format and -z can be used together and repeated, only the last one is considered. Replace `[-z]` in the synopsis of git-repo-info by `[--format=... | -z]`, expliciting that the use of one of those flags replace the other.

2025-10-21builtin/repo: add keyvalue and nul format for structure statsJustin Tobler
All repository structure stats are outputted in a human-friendly table form. This format is not suitable for machine parsing. Add a --format option that supports three output modes: `table`, `keyvalue`, and `nul`. The `table` mode is the default format and prints the same table output as before. With the `keyvalue` mode, each line of output contains a key-value pair of a repository stat. The '=' character is used to delimit between keys and values. The `nul` mode is similar to `keyvalue`, but key-values are delimited by a NUL character instead of a newline. Also, instead of a '=' character to delimit between keys and values, a newline character is used. This allows stat values to support special characters without having to cquote them. These two new modes provides output that is more machine-friendly. Signed-off-by: Justin Tobler <jltobler@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
2025-10-21builtin/repo: add object counts in structure outputJustin Tobler
The amount of objects in a repository can provide insight regarding its shape. To surface this information, use the path-walk API to count the number of reachable objects in the repository by object type. All regular references are used to determine the reachable set of objects. The object counts are appended to the same table containing the reference information.

2025-10-21builtin/repo: introduce structure subcommandJustin Tobler
The structure of a repository's history can have huge impacts on the performance and health of the repository itself. Currently, Git lacks a means to surface repository metrics regarding its structure/shape via a single command. Acquiring this information requires users to be familiar with the relevant data points and the various Git commands required to surface them. To fill this gap, supplemental tools such as git-sizer(1) have been developed. To allow users to more readily identify repository structure related information, introduce the "structure" subcommand in git-repo(1). The goal of this subcommand is to eventually provide similar functionality to git-sizer(1), but natively in Git. The initial version of this command only iterates through all references in the repository and tracks the count of branches, tags, remote refs, and other reference types. The corresponding information is displayed in a human-friendly table formatted in a very similar manner to git-sizer(1). The width of each table column is adjusted automatically to satisfy the requirements of the widest row contained. Subsequent commits will surface additional relevant data points to output and also provide other more machine-friendly output formats.

2025-08-17repo: add the --format flagLucas Seiki Oshiro
Add the --format flag to git-repo-info. By using this flag, the users can choose the format for obtaining the data they requested. Given that this command can be used for generating input for other applications and for being read by end users, it requires at least two formats: one for being read by humans and other for being read by machines. Some other Git commands also have two output formats, notably git-config which was the inspiration for the two formats that were chosen here: - keyvalue, where the retrieved data is printed one per line, using = for delimiting the key and the value. This is the default format, targeted for end users. - nul, where the retrieved data is separated by NUL characters, using the newline character for delimiting the key and the value. This format is targeted for being read by machines.

2025-08-17repo: declare the repo commandLucas Seiki Oshiro
Currently, `git rev-parse` covers a wide range of functionality not directly related to parsing revisions, as its name suggests. Over time, many features like parsing datestrings, options, paths, and others were added to it because there wasn't a more appropriate command to place them. Create a new Git command called `repo`. `git repo` will be the main command for obtaining the information about a repository (such as metadata and metrics). Also declare a subcommand for `repo` called `info`. `git repo info` will bring the functionality of retrieving repository-related information currently returned by `rev-parse`. Add the required documentation and build changes to enable usage of this subcommand.
